Years ago, disaster relief was regarded as sacrosanct. You appropriated aid first and worried about how to balance the federal checkbook later. But that's unlikely to be the case this time around. It was, after all, Mr. Trump's own budget director, Mick Mulvaney, who, as a member of Congress, proposed financing Sandy relief with across-the-board cuts to discretionary programs. Texas Republicans like Sen. Ted Cruz falsely decried Sandy aid as costly pork barrel spending when there was actually precious little of that in the appropriation. Will offsets be required this time around?
